Block-cutting gangsaw for cutting granite or other hard materials and corresponding cutting method

摘要

Block-cutting gangsaw with vertical frame for cutting granite or other hard materials, comprising a blade-holding frame (19) that is supported with the possibility of reciprocating movement on an independent oscillating frame (40) which imparts the oscillating movement to it, so that each blade (20) of blade-holding frame (19) is always in contact with workpiece (18), and the contact area moves along a convex, curved trajectory.
